Elbow Dysplasia (ED) is similar to HD
in that there is thought to be a strong genetic influence, although
factors such as diet and exercise can influence the outcome. As
with HD, the absence of lameness does not
necessarily mean the dog is free of problems, and the only way to
elbows with certainty is by x-ray. ED

for each elbow (unlike HD, the scores are not normally added together
Border Collies are not a breed thought
to be at risk, however the guidance from the BVA is that dogs should
bred from which have Normal elbows, or minimal ED, in order to ensure
risk for the progeny developing any problems.
The procedure and the prices are the
same as for HD, and there is a discount from the BVA on the price of
